Bounds of Coefficient Functional of Certain Subclasses of Analytic Functions Associated with Cardioid Domain

In the present paper with the aid of subordination, the authors introduce a new subclass of univalent functions namely; starlike functions with respect to symmetric points linked with cardioid domain defined by Sₒ, ₄^**: = \ f S: 2zf^{ (z) f (z) -f (-z) 1+zeᶻ=: p (z) \}, where the function p (z) maps unit disk D: =\{z C: |z|
